Yes, you can record DVB and store it without needing to do any video
encoding. You can record all the channels on a single multiplex (frequency,
roughly) at once using a single tuner.

Yes, and indeed that is the way most people outside North America use MythTV
these days.
No idea about DVB-T2. A quick glance at the Wikipedia article makes it
sound like some of the characteristics of the radio layer are changing,
which would mean existing DVB-T cards wouldn't work. In Australia we have
HDTV over DVB-T working just fine, but we don't have the massive number of
channels per multiplex that you have, generally only 2xSD 1xHD per
multiplex.
